污水重金属离子处理技术的研究进展

摘要

Heavy metal pollution in wastewater can cause serious health issues and damages to ecosystem, many technologies have been developed to treat different heavy metals. The harm of heavy metal pollution was briefly discussed, the research progresses and the principles of four heavy metal treatment technologies were reviewed: physico-chemical treatment, adsorption treatment, microbial treatment, membrane treatment. Their main advantages and limitations in application were evaluated, meanwhile the future development of heavy metal treatment technology was proposed.%水中重金属污染对人类健康和生态环境造成了严重的危害，针对不同的重金属离子已经发展出许多处理技术。本文介绍了污水中重金属离子的危害，并综述了物理化学法、吸附法、微生物法和膜分离法的机理和研究进展。对上述处理方法在应用中的主要优点及存在的局限性进行了评述，同时阐述了未来污水重金属离子处理技术的发展方向。
